Well, if people can copy my tweets without permission I can't make a living anymore and I will have to stop tweeting... Nope, that's not coming out quite right. I dunno, where does the triviality boundary lie? If I put together green shirt and blue jeans, do I now "own" the style for having invented it? Surely not. Maybe grellas will enlighten us on how long does a work has to be before it's considered "an original work".
